Title: Panoramic interactive system
Inventor: SMITH GRAHAM T
IPC: G03B37/02
Filed: 1989-12-11
Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to a method and apparatus for recording of a panorama or large portion thereof in a manner for display or selective display of a portion thereof on a video display device.  The method initially records the panorama in a manner not suitable for video display and thereafter projects the recorded image and records the projection of the panorama in a manner suitable for selective reproduction on a video display device.  The method and apparatus are particularly suitable for recording of real time panoramas where the initial recording is time dependent and occurs quickly with sufficient accuracy for effective recording of the panorama, allowing the projecting step and second recording step to be independent of the initial demanding time restraint.  Staging the recording of the panorama simplifies the recording and allows specialization of the steps to improve the quality of the final reproduction.  The apparatus includes a panoramic lens in combination with a camera arrangement for producing an initial record of the panorama.  A projecting arrangement produces an image of the panorama recorded on record, which image is recorded by a recording device in a manner suitable for video display.

Title: Catalytic reforming of alkyleneamines to linearly-extended polyalkylenepolyamines
Inventor: BOWMAN ROBERT G
IPC: B01J23/30
Filed: 1989-12-19
Abstract: ABSTRACT       A process for reforming alkyleneamines to pre-dominantly linearly-extended polyalkylenepolyamines comprising contacting an alkyleneamine or mixture thereof with a catalyst under conditions such that a mixture of polyalkylenepolyamines enriched in linearly--extended products is formed, said catalyst containing at least one compound selected from the group consisting of (a) Group VB metal oxides, (b) Group VB metal phosphates, (c) silicates of Groups IIA, IIIB, IVB, VB, and the lanthanide and actinide metals, and (d) tungsten oxides, with the proviso that the silicates and tungsten oxides are essentially free of aluminum.  For example, ethylenediamine is contacted with a catalyst of niobium phosphate or niobic acid under reaction conditions to yield predominantly non-cyclic polyethylenepolyamines. Unlike the prior art processes, the present process does not require the neutralization of hydrohalide salts and the disposal of a waste metal stream and does not 34,793-F     produce water as a by-product.  This process gives a high selectivity to linearly-extended polyalkylenepolyamines and simultaneously, a low selectivity to undesirable cyclic products.     34,793-F

IPC: G01S11/10
Filed: 1990-03-23
Abstract: THE ABSTRACT    To reduce error introduced by the local oscillator in the velocity calculations, the receiver has two "tracking channels" and a microcomputer.  With numbers required to, simultaneously, lock each of the "tracking channels" each to a respective satellite signal, the microcomputer employs a differential doppler technique to calculate the receiver velocity.  The microcomputer calculates a number which represents the difference between the apparent doppler frequency shift of the carrier signal which is transmitted by the first "tracking channel" satellite and which is measured over a specific time period and the apparent doppler frequency shift of the carrier signal which is transmitted by the second "tracking channel" satellite and which is measured over substantially the same time period.

Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member.  The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.

Abstract: An Inverse Multiplexer is disclosed which first demultiplexes a first data rate input signal into a plurality of second lower data rate subsectional signals, where each subsectional signal is provided with a periodic synchronization marker and includes a data rate which is less than the channel data rate used to transmit that subsectional signal to a remote terminal. Programmable Multiplexers (PMUXs) thenoperate to each take one or more subsectional signals that are (1) clock synchronized to a PMUX clock, and (2) a rational fraction of the channel data rate, and map contiguously assigned time slots in a capacity domain frame for each subsectional signal to time slots of a time domain frame format using a 2-step or 3-step digit reverse technique. The resultant time domain format has the input subsectional capacity domain time slots substantially uniformly distributed over the time domain frame. At the receiving end, an Inverse Demultiplexer performs the reverse operation to recover the original first data rate input signal.

Abstract: A horn for coupling high frequency vibrations from an electroacoustic converter unit to a workpiece, such as is used for welding thermoplastic workpieces by ultrasonic vibrations, is constructed by machining sections of the horn and welding the sections together using electron beam welding or laser beam welding. The respective sections can be made from bar or plate stock. This construction eliminates the machining of deep, inaccessible slots, and as most of the surfaces to be machined are accessible, a fine surface finish can be provided, thus eliminating tool marks which cause the existence of areas of high mechanical stress concentrations when the horn is rendered resonant. Also significant economic advantages are achieved when manufacturing large, massive slotted hums in this manner.
